Introduction to Machine Learning in R

In our Introduction to Machine Learning in R course, you will learn the fundamentals of machine learning. We’ll cover concepts such as K-Nearest Neighbors (KNN) Algorithms and learn about error metrics such as the Mean Squared Error and the Root Mean Squared Error. You'll also learn about hyperparameter optimization, a technique used to optimize machine learning algorithms to boost the accuracy and performance of trained models. And you’ll dig into some k-fold cross-validation to perform more rigorous testing for your model.

Throughout this R machine learning course, you won’t just learn how to use these models, you’ll also build an understanding of what is happening in the model training process. You'll get an introduction to caret, a machine learning library for the R programming language.

As you learn these new skills, you’ll be working with AirBnB prices data from Washington D.C. to predict the optimal price for becoming generating profit from a D.C. home rental.

At the end of the course, you'll complete a portfolio project in which you will use the K-Nearest Neighbors algorithm to predict car prices. This project is a chance for you to combine the skills you learned in this course and practice the machine learning workflow. This project also serves as a portfolio project that you can showcase to your future employer.

By the end of this course, you'll be able to:

Understand and explain the basics of machine learning.

Understand the common pitfalls in machine learning and how to avoid them.
